What is the highest immigration authority in China that the public can report fake visa/illegal stay to?
I need to report somebody who is staying in China illegally. The problem is that they bought a fake visa off the police in order to stay once their contract ended. Therefore, if I report it to the police, it will go through the local bureau, who will obviously not investigate it or do anything about it.
Does anybody know the best way to deal with this? Avoiding the police to begin with so at least it is very hard for them to cover it up/dismiss the case?
